The problem with techno-thrillers is that they age quickly, and they rarely enjoy any kind of longevity. They rely on the technology of their time and attempt to exploit the implications by projecting ominous predictions. Of course, in hindsight, they rarely get it right and most of them become “retro” if they aren’t completely lost in obscurity.

Directors Henry Joost and Ariel Schulman arrived on the scene in 2010 with their ambiguously terrifying documentary Catfish, and they continue to explore the dangers of the online world with this new kinetic thriller.
